In App Purchase Failed “Cannot connect to iTunes Store” error - ios

Question

I am facing this issue since last two months
My App is live with auto-renew InApp purchase before it was working fine then many user complained that when they click on Buy Button Nothing happens so i debug my code and run on my real device I found this error
failed SKPrdouctName
Error Domain=SKErrorDomain Code=2 "Cannot connect to iTunes Store" UserInfo={NSLocalizedDescription=Cannot connect to iTunes Store}
i did not change any code
i did not upload new build
My product is also Approved on Appstore Connect
I did not change anything on the product
I already tried Restarting device, clear caches, login logout apple id still getting the same error
This is happening to many live users
I really need a solution to this
func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
print(response.products)
products = response.products
for product in response.products {
print(product.localizedTitle)
}
}
func request(_ request: SKRequest, didFailWithError error: Error) {
print(error.localizedDescription)
}
func requestDidFinish(_ request: SKRequest) {

Global.sharedInstance.isConsiderPurchasedOrNot = true
}
}
func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
print(transaction.transactionState.status(), transaction.payment.productIdentifier)
switch transaction.transactionState {
case .purchasing:
break
case .purchased:
Miscellaneous.APPDELEGATE.window!.stopMyToastActivity()
if Global.sharedInstance.isConsiderPurchasedOrNot{
print(transaction.payment.productIdentifier + "is purchased")
let prodID = transaction.payment.productIdentifier as String
if prodID == MyProducts.autoRenewSubscription
{
Global.sharedInstance.isPurchased = 1
purchaseSubscriber(usediD: Global.getUserID())
}
}
break
case .restored:
print(transaction.payment.productIdentifier + "is purchased/restored! hello ")
// let str1 = UserDefaults.standard.string(forKey: "username")
Global.sharedInstance.isPurchased = 1
let prodID = transaction.payment.productIdentifier as String
Miscellaneous.APPDELEGATE.window!.stopMyToastActivity()
if prodID == MyProducts.autoRenewSubscription
{
Global.sharedInstance.isPurchased = 1
}
case .failed:
print(transaction.payment.productIdentifier + "is failed!")
Miscellaneous.APPDELEGATE.window!.stopMyToastActivity()
default: queue.finishTransaction(transaction)
}
}
}
